How much do you tip?

[sanantone]

I try to tip with cash, but I have to admit that sometimes I have to tip with my debit card because I neither have nor do I hardly ever need to have cash on me. But, you should tip with cash when you can because there could be miscalculations when the restaurant owner/manager pays out credit card tips, some owners steal tips, and some owners make their servers pay for the credit card transaction fee out of their tips. It's amazing that owners would do these things when they're only paying their servers a couple of bucks an hour, but there are a lot of greedy people out there. It's just another example of how the American tipping culture is really just about employers being cheapskates.
